game was working fine in the morning, now i can only play 2 or three turns before CTD i checked the erro log and this is what i got

Debug Message: RequestEndTurn PlayerObjectID 56, Turn #2
Debug Message: IGC3Player::RequestEndTurn playerID 56
Debug Message: IGC3Player::GetAndClearClickedRequestEndTurn 56
Debug Message: OnStartTurn
Debug Message: SetAITrigger

Tried verifying the cache in steam and it downloaded 3 files then same crash occurred again

verified again and once again 3 field failed to validate and were downloaded. is something deleting files in my game on launch? i am using some mods but none affect any visuals models or sound so that seems unlikely
